Application filed May 10, 1909. Serial No. 495,122.

vaporization of crude oil for purposes offuel for steam boilers and the like.

The objects of my invention are to provide a device of the kind described which will be economical of construotiomnot liable to get out of order or repair, and which will accomplish a vaporization of the oil and the discharge or delivery of the combustible gases therefrom, of such equable and uniform quality and quantity that the combustion therefrom will be constant and complete. These and other objects which will become apparent as the specification of my invention proceeds, are accomplished by the new combination, construction and arrangement of parts described herein, illustrated in the accompanying drawings, and clearly defined in the appended claims.

Similar letters of reference refer to corresponding parts throughout the several views in the drawings, in which- Figure 1 is a front view of my improved oil vaporizer. Fig. 2 is a central sectional view of my improved'oil vaporizer, and Fig. 3 is a side view showing my invention installed in operative position.

The chest A is preferably of globular form and provided in one side thereof is the threaded opening B into which is screwed the hot air pipe C. The opening D is provided in the side of the said chest opposite the hot air pipe, and in the said opening D is screwed the oil inlet pipe E; Centrally between the aforesaid openings and extending at a right angle thereto are disposed the inlet steam conduit F and the conduit G. Each of these conduits is formed integral with the wall of the chest A and their outer ends are threaded to receive suitable connections for the inlet pipe H, and the discharge pipe I, respectively. The innerends of the conduits F and G are so terminated with reference to each that there will be a small distance or 0 en space between said ends find substantia y opposite to the open- The novel and peculiar form, construction of my invention are accom lished,-are shown plainly in Fig. 2, which wi 1 now be referred to. Provided in the conduit F is the perforation J the inner end of which is slightly flared and which leads to the perforation K in the conduit G. The mouth of this perforation K at its inner end is of diameter larger than that of the mouth of the perforation J. The perforation K is of tapered form it being gradually decreased in diameter to the throat L and then of gradually increased diameter to the outer end of the conduit.

In the installation of my invention into operative position the hot air pipe C is passed through the wall of the boiler M and into the firing chamber and the discharge pipe I will project into the firing chamber of the boiler. In oil Vaporizers wherein a jet of steam is used in combination with an ordinary inlet of air, a artial vaporization only of the oil is accomp ished, the result being a fluctuating supply of combustible mixture, and the consequent failure of combustion and then the dangerous uncontrolled flow of gas and of re-ignition. To accomplish the more complete and elfective vaporization of the oil, I provide the pipe or conduit to take the hot air from the firing chamber direct into the chest where as it mingles with the steam and oil such vaporization is effected that there is asteady and uniform delivery into the firing chamber of a gas that is highly combustible and of high efliciency'.

To operate my invention, the oil valve N, after the usual initial heat is generated in the firing chamber of the boiler, is opened.

and arrangement of parts constituting my improved vaporizer'and whereby the results Then steam is introduced by opening the in its passage through the perforations J and K on the hot air and oil affected thereby,

and such vaporization of the fuel is pro duced that the combustion in the firing chamber is uniform and complete. A clean uniform and hot lire is the result, and there will be no clogging or accumulation in the vaporizer chest.

The preferable manner of installing my invention for operation is that shown in Fig. 1, however by reason of the improved suction through the oil pipe that is accomplished, my invention will operate successfully ,with the oil inlet and air inlet disposed horizontally as well as in the vertical position as shown, and the oil will be drawn into the chest uniformly and correctly with- I out reference to the location of the source so variable and uncertain and the delivery of same is so unsteady and unreliable that frequent failure-of the combustion occurs and explosions with their attendant dangers are frequent.

My invention is of especial utility for the utilization of crude or refuse oil of the heavier grades, and by my invention such a uniform and equable vaporization of such crude or refuse oil and such steadyand unvarying delivery of the combustible mix ture or gas are accomplished that the combustion from such vaporization is complete, and there will be no precipitation on the fines and inner lining of the firing chamber, so objectionable where the fuel is not completely vaporized.

By the preferalile arrangement and connection of the steam pipe H with a T-connection 1 having the removable plug Q, as shown in Fig. 3, easy access to the interior of the perforation K is afforded. The object of this arrangement is to render easy the dislodging by a suitable implement of any hard foreign substance such as a fragment of wood or mineral or rock as might occur, in the refuse oil oeing used.

What I claim as my invention and desire to secure by Letters Patent of the United States, is

1. In a device of the kind described, the combination of a hollow chest, a conduit passed through the said chest and being divided transversely upon the interior of said chest to form an inlet conduit and anoutlet conduit, the bore of said inlet conduit being flared to increased diameter at the inner end of said conduit, and the bore of the outlet conduit having a mouth of diameter larger than that of theinlet conduit, an oil inlet through the wall of said hollow chest at a point opposite the space between the interior ends of the inlet and outlet conduits, and an air inlet through the wall of said hollow chest at a location aside from said space between the ends of the aforesaid conduits.

2. In a device of the kind described, the combination of a hollow chest, a conduit passed through the said chest and being divided transversely upon the interior of said chest to form an inlet conduit and an outlet conduit, the bore of said inlet conduit being flared to increased diameter at the inner end of said conduit, and the bore of the outlet conduit being tapered to smaller diameter and then flared to increased diameter at the outer end of said outlet conduit, havinga mouth of diameter larger than that of the inlet conduit, an oil inlet through the wall of said hollow chest at a point opposite the space between the interior ends of the inlet and outlet conduits, and an air inlet through the wall of said hollow chest at a location aside from said space between the ends of the aforesaid conduits.

3. A. device of the kind described, comprising a globular chest having an inlet conduit and an outlet conduit formed integral with the opposite walls of said chest, the

inner ends of said conduits being so disposed as to register with each other but there bcmg an open space between them and aside from the center of said chest, the bore of said inlet conduit being flared to increased diameter at its inner end, and the bore of the outlet conduit having a mouth that is of diameter greater than that of the bore of the inlet conduit, and which said last named bore is tapered to smaller diameter and then flared to increased diameter toward the outer end thereof, an oil inlet through the wall of said chest at a point substantially opposite the open space between the inner ends of said conduits, and an air inletthrough the wall of said chest at a point aside from the said open space, substantially as described.

4. In a crude oil vaporizing apparatus for steam boilers, the combination of a hollow chest having an oil inlet and an air inlet therein, a conduit passed through the said chest and being divided transversely upon the interior of said chest to form an inlet conduit and an outlet conduit, the bore of said inlet conduit being flared to increased diameter at its inner end, and the bore of the outlet conduit having a mouth that is of diameter greater than that of the bore of the inlet conduit, and which last named bore is tapered to smaller diameter and then flared to increased diameter toward the outer end of said outlet conduit, a firing chamber, a pipe connected to the outer end of the outlet conduit and extended into the said firing chamber, a fire box, and a pipe leading from the fire box of the boiler into the air inlet, substantially as'iand for the 'mi'poses described.

In testimony whereof I sign my name to this specification in the presence of two subscribing witnesses.
